At home, Tae Soo is a nurturing dad and devoted husband but, at work, he is a cold-blooded mobster who metes out punishment and engages in bloody turf battles. While he is a dutiful son to his mother and takes care of all of her needs, he is a middle-aged married man, who cannot depend on his own kids to do the same for him in his old age. He is also in an awkward situation in the gang where he takes orders from the former gang boss and kingmaker while his young gang lieutenants are angling for his job. Tae Soo is trying to do what is best for his family while he has to evade the authorities who keep tabs on his gang activities, waiting to pounce on him once they obtain hard evidence of his criminal activities. “What is so evil about being a mobster? It’s all about making a living!” That’s how Tae Soo sees it. (Source: MBC)
